Movement stopped?

**Trigger warning**

Hey guys I’m 19 weeks 1 day with my second baby! I started to feel the baby move about a week to a week and a half ago, but the past couple of days I haven’t felt the baby move. The movement I’ve felt so far has been more of what only I can feel from the “inside” and not so much my husband from the “outside” when he puts his hand on my belly. I’m getting nervous that I haven’t felt anything in a few days and looking it up I’m getting mixed advice. I’m gonna call my OB in the morning but has anyone experienced anything like this? Should I be worried? Any advice would be appreciated!
